I agree completely that now is the only important time in our lives, since every other time is nothing more than a continuation of now (created by our personal and collective now), even as I try to consider all future possibilities when I make decisions that will affect my future. I see the past as “previous nows” and the future as “future nows” – and I really like the concept that time is measured only by humans and that everything is present to the Lord. I understand the philosophical arguments against that view, but I like the idea that dealing in the present is critical because, “Sufficient unto tomorrow is the evil thereof” – or whatever the exact quote is.
The Buddhist concept of karma is wonderful in this regard – and it is badly misunderstood by most people.
